HENRY O. HANSEN, OF OSIIKOSH, \VISOONSIN.

PUMP.

SPECIFICATION forming part of Letters Patent N 0. 581,719, dated May 4,1897. Application filed November 10,1896. Serial No. 611,667. (Nomodel.)

To all whom it may concern:

Be it known that I, HENRY O. HANSEN, a citizen of the United States,residing at Oshkosh, in the county of \Vinnebago and State oflVisconsin, have invented certain new and useful Improvements in Pumps;and Ido declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others'skilled in the art to whichit appertains to make and use the same.

My invention has relation to improvements in pumps; and the object ofthe invention is to simplify the construction and increase thedurability of the pump.

To these ends the novelty consists in the construction, combination, andarrangement of the same, as will be hereinafter more fully described,and particularly pointed out in the claim.

The figure in the drawing is a perspective view of my improved pump.

1 represents the usual cast-iron standard, having spout 2, and 3represents the vertically-reciprocatin g piston-rod, the upper end ofwhich is secured in a socket 4. on the lower end of the connecting-rod5, extending up to a windmill or other motor. A strap 6 encompasses therod 5, forming a guide therefor, being secured to the verticalprojecting arms 7 7 of the bracket 8, encompassing the standard and adjustably secured thereon by bolts 9 9 and 10.

12 represents the pumpdiandle, pivoted at its forward end to the rod 5and fulcrumed in one of a series of holes 13 13 on a bolt 14, secured inthe upper end of a lever 15, which extends downward between the parallelarms of the bracket 8, its lower end fulcrumed on a bolt 16, secured inthe arms 17 17 of a clamp 18, adjustably secured by bolts 19 19 to thepump-standard 1. The same bolt 16 also engages the parallel ea-rs 2O 20of the brace 21, which extends downward and outwardly at an angle to thestandard, and its foot 22 is secured to the floor or platform by alagscrew 23.

An important advantage of my construction is that the handle, which ismounted on the movable fulcrum secured in the clamp 18, can be adjusted'to any position with reference to the spout by simply looseningthe clamp 18 and bracket 8.

Another advantage is that the entire strain is taken from the clamp 18and transferred to the brace 21, and incidentally the fact that thehandle is fulcrumed in the upper end of the lever 15 preserves astrictly vertical movement of the piston-rod, preventing wear and tearon the rod and the tendency to wear the stuffing-box gland oval, as isfrequently the case in this class of pumps where the fulcrum of thehandle is stationary.

Although I have specifically described the construction and relativearrangement of the several elements of my invention, I do not desire tobe confined to the same, as such changes or modifications may be made asclearly fall within the scope of my invention without departing from thespirit thereof.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, 1s-

The pump-standard 1, the piston-rod 3, wrtically reciprocating in saidstandard, the bracket 8 encompassing the upper end of the standard andadjustably secured thereto by the bolts 0 9 and formed with the integralvertical diverging arms '7 '7, a guide-strap 6 horizontally secured tothe upper converging ends of said arms, and the extension 5 of the rod 3passing through said guide-strap in combination with the horizontallyadjustable clamp 18, the brace 21 having its upper bifurcated endencompassing the horizontal arms 17 17 of said clamp and pivoted theretoby the fulcrunrbolt 16, the vertical lever 15, having its lower endfulcrumed in said pivot-bolt l6, and the handle 12 fulcrumed on the bolt14, secured in the upper end of the lever 15, and having its outer endpivoted in the lower end of the extension 5, substantially as shown anddescribed.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

HENRY O. HANSEN.
